Toledo – Ryan Ketchner (LHP)
Over the last two years, the Tigers have given left-hander Ryan Ketchner an opportunity to come back from injuries, and his recent success may be showing that the Tigers patience is finally paying off. In five starts throughout June, Ketchner was superb, tossing 29 innings and allowing just 28 hits and five walks, while striking out 25 in the process. His performance was good enough for a 2-0 record, and a 2.17 ERA, and it has his season ERA down to 3.41 as of this writing.

Erie – Zach Simons (RHP)
To say it's been an interesting year or more for Simons, would be a drastic understatement. He's gone from the Tigers 40-man roster, to being removed in the off-season, to battling cholera after a stint in Venezuela this past winter, to being at full strength again and proving nearly unhittable at Double-A. Simons saw action in eight games during June, posting a miniscule 0.77 ERA and allowing only seven hits and three walks over 11 2/3 innings of work.

Lakeland – Adam Wilk (LHP)
Wilk has done little other than dominate opposing hitters since signing with the Tigers last summer. He posted sub-2.00 ERAs at both Oneonta and West Michigan in 2009, and after a rocky month of May, he was back on track again in June, posting a 2.23 ERA over five starts; including one complete game effort. Wilk tossed 32 1/3 innings, allowing 33 hits and an unreal two walks, while striking out 20 and keeping the ball in the yard by allowing just one home run.

West Michigan – Zach Samuels (RHP)
After starting the year in extended spring training, Samuels – an undrafted free agent in 2009 – finally got his first crack at the Midwest League, and he wasted no time getting rolling. In eight relief appearances last month, Simons spanned 21 innings with just 14 hits and two walks allowed; enabling him to keep his ERA at a sparkling 0.43 mark. Simons has not allowed a home run since his first outing in West Michigan back in May, and he only allowed one earned run the entire month of June.

DSL Tigers – Jorge Medina (LHP)
The 20-year old Medina was signed at the start of the DSL season to help the load off what projected to be a very raw pitching staff, and he's done that and then some this season. Medina took the mound eleven times last month, including one start, and he finished with a 3-1 record and 1.44 ERA. In 25 innings, Medina allowed just 165 hits, no home runs, and 11 walks, while fanning a robust 29. Opposing hitters managed just a .180 batting average against in June.

VSL Tigers – Juan Espinoza (LHP)
One of the VSL Tigers promising young starters, Espinoza posted a shiny 2.00 ERA in his first two starts backin May, and then set out to improve upon that in June. Espinoza pitched in six games last month, making four starts, and saving one other contest, and he finished the month with a 1-0 record. His 1.13 ERA is sound evidence of his success, as in 25 innings he allowed just five walks and struck out 13.
